. e (c1. 12s- 93) My invention relates to animprovement in hot waterheaters and has for one purpose the provisionfof an oil burning hot water heater which shall be economical to manufacture and eilicient in use.

Another purpose is to provide improved means for lighting the llame and inspecting the flame.

Another purpose is to-provide improved means for removably 'securing the burner in position.

Other purposes will appear from time to time in the course of the specication.

I illustrate my invention-more or less diagram- Fig. l is a side elevation: Fig. 2 is a section on the line 2-2 of Fig. l;

Fig. 3 is a section on an enlarged scale on the line 3-3 ofFig. 2;.and V Flg.4isadetail.. i 1 4Like parts' are indicated by like symbols throughout the specification and drawing.

Referring to the drawing. I illustrate, for e'xample, a drum type .hot water heater, in which I Vmay employ, for example, a cylindrical outer shell I, having'a bottomv member 2, a top member 3, a central passagefl, and a lower partition 5.

- A water inlet is-indicated at 6.V and an outlet at 1. The details of the heating space or the coils,

.and the subjection of the water to the heat of the burner are not indicated, as they do not of themselves form part of the present invention. What is essential is that whatever heat exchange mechanism may be employed, there shall be a preferablyk axial opening from top to bottom of theinterior of the drum I, whichis diagrammatically indicated as the passage 4.

Access may be had to the space in the drum below the partition 5, for example, through any suitable door aperture III, closed by the removable door II, which may be hinged as at I2, and provided with any suitablel latch I3. The door may be made entirely removable if desired.

I4 generally indicates a pot type burner having a slightly concave bottom I5, adapted to receive a liquid hydrocarbon delivered along the passageV It, which may extend through the drum wall I i and may be provided with any suitable removable securing means I1, whereby the burner I4 may be readily secured to or removed fromthe end of the fuel passage Il, which may for example be vof ilexible copper tubing.

The burner I4 is shown inlets II. The arrangement of air inlets is not matically inthe accompanying drawing wherel Y as having a generally cylindrical wall provided with-a plurality of primary air inlets -Il and a top row of secondary air` burners. What is' essential is that the burner of the essence of the present invention, as it may be applied to a wide variety of diilerent types of shouldhave an open top aligned with the vertical passage or space 4, and shall have some interiit- A ting means, flange or the like, asy indicated as at 20, whereby it may abut snugly against the bottom of the partition 5, or some abutment portion thereof.

In order both to center the pot I4 land to secure it in position, I provide a lever` structure, indi` cated as composed of two arms 2| and 22, which 'may be of spring stock, rod stock, or the like. vThese arms are pivoted for example to brackets 23, located in the inner face of the wall I, gener- 1` allyopposite to the door II. The arms 2| and 22 are shown as secured to each other at their free endsto provide what is in effect a V-shaped spring lever. Pivoted to the end of the V is a compression member or link, which may include ltwo screw-threaded members 24, 25, the member 25 vbeing provided with lan eye 26, through which the lever structure passes. This is shown merely as one practical form of the structure, as

it may be widely varied. The .link 'may be adjusted for length by rotation of the nut 21, to l which the members 24 and 25 are screw threaded. Any suitable forkor head 28 may be provided for the bottom of the member 24, and is adapted to engage-any suitable ange or abutment, herein indicated as at 29, located within the door aper ture. It desired, the lower edge of the door frame may itself be employed as such an abutment.

In order to center the pot for quick insertion,

I provide abutments 30, 3l, which are shown as adjustable along the arms 2l, 22. They may be properly adjusted for any size of heater or pot, and held in positionby set screws 3| a. When so adjusted, and when the door is open andthe lever structure is in the dotted line position of Fig. 2, the -pot is simply pushed in through theA .door and slid along the lever structure until it j vstrikes the abutments 30, 3l. Itmay be turned to the proper position to be secured to the prei.'-

erably flexible loil inlet passage I8. 'Ihe operator then raises the lever, and with it the pot, untilthe pot is properly seated against the partition E,-

or any appropriate abutment member or members associated therewith. .The fork 24 is then engaged` with the abutment 29, or with the -lower frame of the door shown at 29a, and the result is a firm position. The-pot may be very quickly assembled,

thrust of the pot I4 upwardly into tight and very quickly removed for cleaning, replacement, repair, or the like. 'I'he door il may be closed, or ii desired it may be entirely removed.

Aligned with the central passage 4 is a flue structure which includes a vertical portion 40, upwardly extending in vertical alignment with the burner i4 andthe passage 4. 4I indicaltes'a stack member or elbow, and 42 a horizontal member beyond the elbow, which in turn communicates with any suitable flue or stove pipe 53. The angle memberis provided with any suitable aperture 44, which may be closed by a damper vane 45, pivotedas at 46. The vane may be adapted for inspection of the fire and for lighting of the fire. When the damper is in closed position, the height of the unit is such that the operator can -lool: directly downwardly through the hole 41 and see what the flame conditions are. I suggest a hole 41, but it will be understood, of course,

.that any suitable transparent-material may be inserted in the vane or may form part or all 'of aperture in vertical alignment with the burner,

and a damper member for said aperture and including a transparent portion adapted for the visual inspection of the burner when the damper member is closed.

3. In combination, a pot type burner having an open top, a housing a'bove and generally coaxial with the top of said pot type burner, a iiue extending upwardly from the top of the housing. generally coaxial with the burner, a bend in said flue, a hinged damper in said bend, said bend the vane or damper member 45. I may, for example, employ isinglass or the like.

When it is desired to light the fire, all that is necessary is for the operator to open the damper and drop a lighted match down the central passage 4. It drops into the bottomv of the burn--` er and serves as a wick' for igniting the fuel in the bottom of the burner. y

It will be realized that whereas I have describedand illustrated a practical and operative device, nevertheless many changes may be made in the size,` shape, number and disposition of parts without departing from the spirit of my invention. I therefore wish my description and drawings to be taken as in a broad sense illustrative or diagrammatic, rather thanas limiting me to my precise showing.

I claim:

1. In combination with a heater having a genlerally upright centrally open housing, 'an open ent portion adapted for the visual inspection of the burner when the damper member is closed.

2. In combination with a heater having a generallyv upright centrally open housing, an open topped burner located in vertical alignment with the central opening of said housing, a ue extending from the top of the housing, generally coaxial with the burner and said central opening, an elbow in said ue, said elbow having an having an aperture closed by said damper, said aperture and damper being generally vertically aligned with the open ltop of the burner, the space between the damper and the burner being unobstructed, the nre being observable through the damper when the damper is closed.
